[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the laparoscopic aspirator irrigation device connector described herein is a preferred embodiment and is only used for illustration and explanation of the present invention, and does not constitute a limitation thereof.

[0021] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0022] This implementation example Figs. 1-3 As shown, a laparoscopic aspirator irrigation device connector includes a flexible connector 1 for fitting onto the irrigation device connector, and a first rigid connector 2 for sealingly fitting onto the end of the flexible connector 1. At least two second rigid connectors 6 are movably connected to the end of the first rigid connector 2 away from the flexible connector 1. One end of the second rigid connector 6 is detachably and sealingly connected to the end of the first rigid connector 2 away from the flexible connector 1, and the other end of the second rigid connector 6 is used for sealingly connecting to a flexible irrigation tube. The outer diameters of the ends of the at least two second rigid connectors 6 that are connected to the flexible irrigation tube are different.

[0023] Specifically, such as Fig. 2 As shown, the upper end of the flexible connector 1 is used to fit onto the connector of the laparoscopic aspirator irrigation device. The flexible connector 1 is a hollow cylindrical tube. The inner wall of the upper end of the flexible connector 1 has a sloping groove 11 that is compatible with the connector of the irrigation device. In this embodiment, there are 3 sloping grooves 11, which are inclined toward the laparoscopic aspirator irrigation device. The sloping groove 11 can not only make the connection between the flexible connector 1 and the connector of the laparoscopic aspirator irrigation device more secure, but also improve the sealing of the connection.

[0024] The lower end of the flexible connector 1 is fixedly connected to a first rigid connector 2 via a limiting protrusion. The first rigid connector 2 is a rigid circular tube structure, which can be made of metal or plastic. A one-way valve 3 is provided in the first rigid connector 2. The flow direction of the one-way valve 3 is from the second rigid connector 6 to the flexible connector 1, that is, the flow direction of the one-way valve 3 is from bottom to top as shown in the figure. In this embodiment, the one-way valve 3 is a disc-type check valve, that is, a disc that can only rotate upward is hinged in the first rigid connector 2. When the disc is flipped upward, the first rigid connector 2 is open, and the flushing fluid can flow to the laparoscopic aspirator. When the disc is flipped downward to the horizontal position shown in the figure, the first rigid connector 2 is closed. The one-way valve 3 mainly serves to prevent the backflow of contaminated water after flushing. Of course, the one-way valve 3 can also adopt other one-way valve 3 or check valve structures in the prior art, such as a duckbill one-way valve 3, etc.

[0025] The lower end of the first hard joint 2 is movably connected with two second hard joints 6. Specifically, the outer wall of the first hard joint 2 is provided with an annular first mounting groove 22, and the second hard joint 6 is rotatably connected with a soft connecting band 5, the upper end of the soft connecting band 5 is fixedly provided with a first mounting ring 4 which is in clearance fit with the first mounting groove 22, and the first mounting ring 4 is rotatably sleeved in the first mounting groove 22. Since there are at least two second hard joints 6, the groove width of the first mounting groove 22 needs to be greater than the sum of the widths of the first mounting rings 4 of the at least two second hard joints 6, so as to ensure that all the first mounting rings 4 are arranged in the first mounting groove 22, prevent them from falling off from the first hard joint 2, and avoid the loss of parts. The second hard joint 6 is threadedly connected with the end of the first hard joint 2 which is away from the soft joint 1. An internal thread is arranged in the inner wall of the bottom end of the first hard joint 2, and an external thread which is matched with the internal thread is arranged on the outer wall of the top end of each first hard joint 2. In order to improve the sealing performance, a sealing ring can be further arranged at the internal thread and the external thread.

[0026] The second hard joint 6 is a hollow circular tube structure, and is provided with an annular second mounting groove, and a second mounting ring is rotatably sleeved in the second mounting groove. The upper end of the soft connecting band 5 is fixedly connected with the first mounting ring 4, and the lower end is fixedly connected with the second mounting ring. In this way, the second hard joint 6 can be tightly screwed and unscrewed with the first hard joint 2 without being lost. The outer diameters of the lower ends of the second hard joints 6 are different from each other, so that the laparoscope aspirator can be connected with irrigation tubes of various specifications, and the number of the second hard joints 6 can be adjusted according to actual conditions. The outer wall of the end of the second hard joint 6 which is used to connect with the soft irrigation tube is fixedly provided with a plurality of sealing convex rings 61, which can not only prevent the soft irrigation tube from falling off, but also improve the sealing performance.

[0027] When the embodiment is used, as shown in Fig. 3 , the appropriate second hard joint 6 is selected according to the specification of the soft irrigation tube, the upper end of the corresponding second hard joint 6 is tightly screwed with the lower end of the first hard joint 2, and then the soft joint 1 is sleeved on the laparoscope aspirator irrigation joint, and the soft irrigation tube is sleeved on the lower end of the second hard joint 6. The embodiment can be repeatedly used after disinfection.
